Description
Technical Field
The invention relates to the technical field of composite fibers, in particular to a high-strength anti-aging composite fiber for a fly-knitted mesh cloth and a preparation method thereof.
Background
Chemical fiber refers to fiber made from natural or synthetic high molecular substances. Depending on the source of the raw material, the fiber can be classified into artificial fiber using a natural polymer as the raw material and synthetic fiber using a synthetic polymer as the raw material.
Chemical fibers are generally prepared by first forming a natural or synthetic polymeric or inorganic substance into a spinning melt or solution, then filtering, metering, extruding from a spinneret (plate) into a liquid stream, and then coagulating to form the fiber. The fiber is called as nascent fiber, has poor mechanical property, and can meet the requirements of textile processing and use only through a series of post-processing procedures. Post-processing is directed primarily to stretching and heat-setting the fiber to improve the mechanical properties and dimensional stability of the fiber. Stretching is to orient the macromolecules or structural units in the as-spun fibers along the fiber axis; heat-setting is primarily a relaxation of internal stresses in the fiber. The post-processing of the wet-spun fibers also comprises the procedures of washing, oiling, drying and the like. When spinning the filament, winding the filament into a tube through the working procedures; the spinning of staple fibers requires additional steps such as crimping, cutting, and baling.
Polyamides, which contain a number of repeating amide groups in the main chain, are called nylons when used as plastics and as nylon when used as synthetic fibers, are prepared from diamines and diacids, and can also be synthesized from omega-amino acids or cyclic lactams. According to the difference of carbon atom number in diamine and diacid or amino acid, a plurality of different polyamides can be prepared, the variety of the polyamide is dozens, and the polyamide-6, the polyamide-66 and the polyamide-610 are most widely applied.

the difference from example 4 is that the antioxidant is only antioxidant 1010, and is not bis (2, 4-di-tert-butylphenyl) pentaerythritol diphosphite, and the rest is the same as example 4.
The performance tests of the high-strength aging-resistant composite fibers for the fly-woven mesh cloth obtained in examples 2 to 4 of the present invention and the composite fibers obtained in comparative examples 1 to 7 were performed, and the test results are shown in table 1.
The Xd aging resistance test is that the high-strength aging-resistant composite fibers for the fly-woven mesh cloth obtained in the examples 2 to 4 of the invention and the composite fibers obtained in the comparative examples 1 to 7 are placed under a halogen lamp with illumination of 1250lx for X days at a distance of 30cm and a temperature of 30 ℃ in an air (aerobic) environment; then, a breaking strength test was performed.
TABLE 1
As can be seen from the above table, the high-strength aging-resistant composite fiber for the fly-knitted mesh cloth has high breaking strength, high strength and good mechanical property; and the aging resistance test shows that the breaking strength is kept basically unchanged, and the high-performance anti-aging material has good aging resistance.
The above is only a preferred embodiment of the present invention, and it should be noted that the above preferred embodiment should not be considered as limiting the present invention, and the protection scope of the present invention should be subject to the scope defined by the claims. It will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the spirit and scope of the invention, and these modifications and adaptations should be considered within the scope of the invention.
